摘要:
The switchgear assembly has a polyphase design and has a gas-filled, modular encapsulation for each phase. Provided as the modules are at least one busbar (51, 52), which is guided predominantly horizontally, a circuit breaker (10) and two combined disconnecting-earthing switches (71, 72, 73) of identical design and having a disconnection and grounding function. A first one (71) of the combined disconnecting-earthing switches supports a section of the busbar (51) and is connected between the busbar (51) and a first current terminal (11) of the circuit breaker (10). The second combined disconnecting-earthing switch (73) is connected between an outgoing feeder (60) or a further busbar of the assembly and the second current terminal (12) of the circuit breaker (10). The combined disconnecting-earthing switches (71, 72, 73) are aligned such that two drive apparatuses (81, 82, 83), which are provided for their actuation, point in the same, predominantly horizontal direction. This switchgear assembly is of compact design since the drives of the combined disconnecting-earthing switches are guided in one direction and sections of the assembly which are connected to the combined disconnecting-earthing switches are guided in the opposite direction. If the drives point towards a control aisle of the assembly, the positions of the drives (81, 82, 83) and therefore the switching positions of the combined disconnecting-earthing switches (71, 72, 73) are visually easily accessible to the operator of the assembly.

A switching chamber insulation arrangement and a circuit breaker having such a switching chamber insulation arrangement are provided. The switching chamber insulation arrangement provides improved heat dissipation in the area of the contact areas of switch contact poles. The switching chamber insulation arrangement includes a strut arrangement having a plurality of struts. Each strut has a first foot area, a second foot, area and a center area which is located between the first foot area and the second foot area, respectively. The struts are arranged along a circumference around a longitudinal extent axis of the strut arrangement. The strut arrangement has a first mechanical coupling area on a side of the first foot areas for coupling to a first pole of a circuit breaker, and a second mechanical coupling area on a side of the second foot areas for coupling to a second pole of a circuit breaker.

A switchgear assembly module has a housing, which forms a common gas space for accommodating an insulating gas for the switchgear assembly module. The switchgear assembly module includes a busbar conductor arrangement having three busbar conductor sections, which are accommodated in the common gas space, an outgoing conductor connection group with three outgoing conductor openings and with three outgoing conductor sections, which extend from within the housing towards a respective one of the outgoing conductor openings, and three switch disconnectors, which each connect a respective one of the busbar conductor sections to a respective one of the outgoing conductor sections via a disconnection point. The disconnection point of a first one of the switch disconnectors is arranged on a first side of an outgoing normal plane and the disconnection point of a second one of the switch disconnectors is arranged on a second side of the outgoing normal plane.

The high-voltage switching device used in one installation position and has metallic encapsulation (10) a switching gap (4) and a particle trap (1) for holding foreign body particles (2), and is characterized in that in the one installation position, the particle trap (1) is arranged vertically underneath the switching gap (4), in the one installation position, an isolator part (8) is provided, which has a surface (8a) aligned essentially horizontally and faces the interior of the high-voltage switching device, with a metallic wall (9), which is higher than the particle trap (1; 1′), being arranged between the isolator part (8) and the particle trap (1; 1′). The particle trap (1) has a viewing window (3). If the high-voltage switching device is a disconnector, this viewing window (3) may be identical to the viewing window (3) for visual access to the visible disconnecting gap (4) of the disconnector. The high-voltage switching device is used particularly advantageously in a second installation position and has a second particle trap, with the second particle trap arranged vertically underneath the switching gap (4) in the second installation position. This results in the high-voltage switching device having good operational reliability and a low susceptibility to defects.

A high-voltage circuit breaker has an interrupter unit, a closing resistor and a switch which is connected in series with the closing resistor. The interrupter unit has a driven first interrupter contact which can move along an axis and interacts with a second interrupter contact, which is arranged on the axis in order to open and close the high-voltage circuit breaker. The switch has a switching contact which can rotate about a rotation shaft (D) and whose rotary movement is coupled by of a link control to the movement along the axis (A1) of the first interrupter contact.
